% Numerical Tic Tac Toe is a variation invented by the mathematician Ronald Graham.
% The numbers 1 to 9 are used in this game. The first player plays with the odd numbers,
% the second player plays with the even numbers. All numbers can be used only once.
% The player who puts down 15 points in a line wins (sum of 3 numbers).
% This game can be generalized to a n × n board.


% In Treblecross, both players play with the same symbol.
% The game is played on a 1-by-n board with k equal to 3.
% The player who makes a three in a row of Xs (or black chips) wins the game

	\maketitle



	We have large tic-tac-toe grid, each cell of which contains another.
	On each turn, one player puts their glyph into a cell of a small grid. When the next player goes,
	they must make their move in the small grid in the same position as the previous player's move.
	\begin{itemize}
		\item The first player to move may pick any small grid to start in.
		\item If a player is directed to a grid that is \textit{full}, that player may go anywhere. \par
		A sub-grid that is \say{won} but not full may still be played in.
	\end{itemize}

	\vspace{2mm}

	The first player to complete a line of three \say{won} subgrids wins the game.
